Seattle Green Builder to Pre-Sale LEED Platinum Prefab Home

Seattle green builder Sloan Ritchie of Cascade Built just unveiled his company’s latest single-family project – one of the city’s first modern prefab modular LEED Platinum homes. In the the heart of Seattle’s Madison Valley neighborhood, and next door to the company’s acclaimed “Alley House” built in 2008, this project will be dubbed the Alley House 2 for its location on another postage-stamp sized infill lot accessible by alley.

“We live in a desirable city where population growth is expected for years to come. Accommodating this growth means building on in-city lots where the focus on space is about quality, not quantity” says Sloan Ritchie.

Designed by award-winning architect David Foster, the Alley House 2 will be prefabricated in modular components by Seattle-based Method Homes in their local production facility, and will target LEED for Homes Platinum certification, the highest certification possible. While a first for Cascade Built Ritchie chose a modular prefab build for the Alley House 2 for its shorter building time frame (approximately 2 months) and the reduction in material waste, which is minimized to less than 5%. The prefab build also means the house will be constructed in a closed environment where exposure to elements such as rain, do not exist.

The Alley House 2 by Cascade Built

The Alley House 2 is ten blocks from Seattle’s newly revived Pike/Pine corridor and new Light Rail station, and just one mile from downtown Seattle. The home features a modern aesthetic and open floor plan that draws ample natural light. Blending luxury with conscious living, the Alley House 2 incorporates durable finishes; healthy indoor air; and low maintenance, high quality finishes, windows and appliances.

Pre-selling the Alley House 2 will allow Cascade Built to work closely with the new homeowner to customize the finishes that most impact their daily life. Among the choices to be made are whether or not to install a solar hot water and/or pv (photovoltaic) system, and a green (living) roof, all of which would work to offset the home’s energy consumption and are included in the design.

The Alley House 2 will have 1,697sf of living space, including 3 bedrooms, and 2 bathrooms, as well as the potential to convert the lower level (including fully conditioned garage) into an Accessory Dwelling Unit. The dates for craning-in of the prefab modules will be publicly announced in October 2011, with completion and scheduled open houses soon after.
